A revolutionary plant that can suck carbon dioxide right from the air was unveiled on top of a waste recovery facility near Zurich on Wednesday. Swiss company ClimeWorks is capturing CO2 from the air with the world's first commercial carbon removal technology. Its Direct Air Capture plant is capable of removing 900 tonnes of CO2 from the atmosphere a year.

Small fans pull air into the collectors, where a sponge-like filter soaks up carbon dioxide. It takes two or three hours to fully saturate a filter, and then the process reverses: The box closes, and the collector is heated to 212 degrees Fahrenheit, which releases the CO2 in a pure form that can be sold, made into other products, or buried underground."
